Title: Apparatus for determining an electrical characteristic of a fibrous dispersion.
IPC: G01N27/07
Filed: 1982-11-08
Abstract: In the formation of a paper web from stock fed to a Foudrinier wire, the Zeta Potential is an important parameter. A measure of Zeta potential is made by measuring the streaming potential developed in a vertically-arranged cell having a horizontal mesh therein on the underside of which a pad of fibres and fines is formed by pumping stock into the lower part of the cell. Electrodes located in the cell above and below the pad are used to obtain a measure of streaming potential at a given pressure differential across the pad. A pressure transducer is mounted in the lower part of the cell. Corrections are made for temperature and conductivity by sensors in the stock feed path to the cell. A microprocessor control and measuring circuit is disclosed which sequences valves for controlling the flow of stock and flushing fluid to the cell and which measures the relevant parameters.

Title: Multi-layer aluminum alloy brazing sheet.
IPC: B23K35/02
Filed: 1983-06-23
Abstract: A composite brazing material is described, composed of a layer (usually an ingot) of high manganese content aluminum alloy (3000 series alloy the "core") and a layer of high silicon content aluminum alloy (4000 series alloy the "cladding") with a layer of aluminum alloy having the following composition: -silicon 6.8-8.2 wgt. % -iron up to 0.8 wgt. % -copper up to 0.25 wgt. % -manganese up to 0.10 wgt. % -zinc up to 0.20 wgt. % -other elements up to 0.15 wgt. % -aluminum balance - disposed between the cladding and core layers and in contact with both. Subsequent hot rolling of the multi-layer composite produces a good bond between the core and the cladding through the intermediate layer. The resulting brazing material has the external properties of a simple two-layer composite of core and cladding without the intermediate layer. The three layer composite of the present invention, however, has a much stronger interlayer bond and is not subject to the serious delamination or bond failures of the prior art two-layer materials. Additional composite layers can also be used, with a layer of the intermediate alloy as described herein placed between each successive pair of the 3000 and 4000 series alloy layers. One typical configuration is composed of a 3003 core, clad each side with 4104 alloy sheets and with a 4343 intermediate alloy sheet on either side of the core between the core and each cladding sheet.

Patent ES-8505019-A1 (ES)
Title: Method and apparatus for conducting wireline operations in a borehole.
IPC: E21B23/14
Filed: 1984-01-23
Abstract: For conducting wireline operations in a deviated borehole, a dual or two-stage locomotive (44) pulls a wireline cable (40) through both the entire length of a drill string (35) and the entire length of a stinger (25) therein to dock with a tool (20) at the bottom of the stinger. The inner or second-stage locomotive then pulls the stinger out into the borehole by pushing on the bottom end of the stinger to prevent buckling the stinger. The stinger and drill stem can be assembled to virtually any length, without requiring pre-wiring. The risk of buckling upon retracting the stinger back into the drill pipe, by pulling on the cable, is reduced by the use of the special configuration provided by the present invention.
